RADIATOR.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application led September 20, 1915. Serial No. 51,607.

To all whom 'it may concern.'

Be it known that I, JOHN B. GABRIELSON,

a subject of the King of Sweden, residing at the city of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Radiators, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to radiators for motor driven vehicles; and the object of the improvement is to provide a core construction for the radiator in which the walls of the water ways are provided with an alternating series of swells and grooves which form spaced narrowed points between the swells, which .conformation furnishes a large radiating surface on a vertical water way; and also to provide zigzag bracing strips between the pairs of corrugated sheet metal strips forming said walls of the water ways, the bends of the zigzag bracing sheet being spaced to alternately engage the grooves in the opposite sides of said sheet metal ways, thereby forming a strong bracing conformation which has a pleasing appearance in front elevation; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is an elevation of the front of an automobile showing the radiator core with the air lues therethrough. Fig. 2 is a perspective View of a portion of one of the water ways showing the swells in the sides thereof and the crosswise grooves which form the spaced narrow necks between the swells in the water ways. Fig. 3 is a partly sectional view in partly front elevation of a portion of the core of the automobile showing the water ways and the bracing construction of the parts. Fig. 4 is a perspective view of a portion of one of the zigzag corrugated sheet metal bracing strips. Fig. 5 is a crosswise sectional view through one of the water ways.

Like numerals of reference refer to corresponding parts in the several views.

The numeral 10 designates the radiator which is made the size desired for cooling the water in the motor. The numeral 11 designates the casing for the core 12 of the radiator, which casing has the reservoir 13 at the top to receive the heated water from the motor for cooling, and the reservoir 14 at the bottom from which the water again goes to the motor after passing through the radiator.

The core of the radiator is made up of substantially vertical water ways 15 which are formed of strips of sheet metal 16 which are bent a spaced distance apart through the lengthwise central portion, the edges 17 being attached to one another -preferably by means of solder. The sides of the spaced portions which form the water way 15 are shaped in alternate spaced crosswise swells 18 and grooves 19 to form alternate enlargements and narrow points or necks in said water ways 15 to thereby delay the flow of the heated water as it Hows through said water ways to cool the same.

Great strength is given to the core 12 by means of the zigza corrugated bracing separating strips 2O 1n which the angular bends are so proportioned that the points 21 engage in the crosswise grooves 19. The grooves 19 in one water way strip 16Aare placed half way between the grooves 19 on the adjacent water way strips 16 to receive the zigzag strip 2O first on one and then on the other water way in said grooves 19. This arrangement of the strips 20 braces the water ways lirmly in position and rigidly holds them throughout their length so that all changes of form from expansion of the metal and from outward shock or vibration are carefully guarded against.

The front of the radiator is given a pleasing appearance by the V-shaped orzi zag corrugations in the strips 20 separated by the vertical lines of the edges 17 of the strips 16 and the air circulates freely through the lines formed by said V-shaped corrugations in the strips 20 on each side of the swells in the water ways 15. The narrow portions 19 of the water ways may be proportioned to the amount of water which it is necessary to deliver from the reservoir 13 to the reservoir 14..

It is obvious that thisforms an exceedingly simple and strong radiator core construction which can be manufactured at small cost and which at the same time gives large radiating surface to a vertical water way and is adaptable to the needs of both large and small radiators.

I claim as`new:

1. In a radiator, a series of connected pairs of plates, each plate being formed with alternating swells and depressions, the

respectivo swells and depressions of tho plates of cach pair of plates being located opposite to each other and conjointly forming continuous water passages, the depressions on the exterior of each pair of plates being located opposite and in spaced relation to the swells on the exteriors of the next adjacent plates, and zig-zag plates in the space between adjacent pairs of plates, the terminals of each of the inclined parts of which zig-zag plates seat in the depressions of the adjacent pairs of plates.

2. In a radiator, a series of pairs of plates, each plate being formed With alter-v nating swells and grooves to provide Water passages, the grooves of the plates being arranged opposite the swells of the adjacent pairs of plates, and spacing plates extending from groove to groove of adjacentplates whereby to form a, series of triangular air passages which alternately face in opposite directions and have open bases each of which latter straddles a single one of the convex faces of the swells of the adjacent pairs of plates, said air passages extending from the convex outer face of one plate of a pair of plates to the groove of the outer face of the adjacent plate of the adjacent pair of plates.

In testimony whereof I have alixed my signature in the presence of two Witnesses.

JOHN B. GABRIELSON.
